INCI: STEARYL ERUCAMIDE
A gentle emollient that helps products feel smooth and creamy, with a very low risk of irritation or clogged pores.
In plain English
Stearyl erucamide is a waxy substance made in a lab. It's added to creams, lotions, and lipsticks to make them feel silky and spread easily on the skin. It also helps keep the product's texture consistent and can make the formula look more opaque or creamy.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
Stearyl erucamide is a synthetic amide derived from stearyl alcohol and erucic acid (a fatty acid found in rapeseed oil). It is a waxy solid at room temperature and is used primarily as an emollient and texture enhancer in cosmetics.
How it works
In a cosmetic formula, stearyl erucamide sits on the surface of the skin, forming a thin, smooth film that reduces friction and gives a silky feel. It also helps thicken the product and can make the formula appear more opaque or pearlescent, improving the visual appeal of creams and lotions.
Pros
Gentle on skin
Stearyl erucamide has a very low irritation and comedogenic rating, making it suitable for sensitive and acne-prone skin types.
Improves product feel
It gives creams and lotions a silky, smooth texture that glides on easily without feeling greasy or heavy.
Cons and cautions
Synthetic origin
This ingredient is lab-made, which may be a turn-off for consumers seeking natural or plant-based skincare.
Limited research
There is not a large body of independent research on stearyl erucamide's long-term effects on skin, though available safety data supports its use.
Best for
- Anyone looking for a gentle, non-irritating emollient
- People with sensitive or acne-prone skin who want a low-comedogenic option
Use caution if
- Those who strictly avoid all synthetic ingredients in their skincare
Usage tips
Safety summary
Stearyl erucamide is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, and no significant safety concerns have been identified in available research or regulatory reviews.
Research notes
Research on stearyl erucamide specifically is limited, but it is chemically similar to other fatty amides that have been reviewed by the Cosmetic Ingredient Review (CIR) panel and found safe. Its primary functions are as an emollient and texture enhancer, with no known toxicity at cosmetic use levels.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has evaluated similar fatty acid amides and found them safe for use in cosmetics.
- Common uses
- Moisturizers, Lipsticks, Hair conditioners, Creams and lotions
- Environmental note
- Stearyl erucamide is synthetic and not biodegradable in all conditions. Its environmental impact is considered low due to the small amounts used in personal care products.
Good to know
- Stearyl erucamide is often used in combination with other emollients and thickeners to achieve the perfect texture.
- It is not water-soluble, so it is typically found in oil-based or emulsion products.
